High sensitivity, can measure gas/steam down to 2m/s

High sensitivity sensor, advanced signal processing technology and best anti-vibration features ensures the meter to provide a 1%RD accuracy even at a super low velocity of 2m/s for gas and steam

Applications:

Compressed air measurement
Vent air measurement.
HVAC pipeline air measurement
Measurement of other process gases
Gas drainage in coal mines
Measurement of liquids, especially of non-conductive liquids
